Yea, Bellevue used to be amazing service. With the latest flood of Model 3's (somehow only a year into production with no scheduled maintenance, a whole lot of them need service), corporate belt tightening, and generally increased Elon's chaos, the quality is going down fast. Had my car in service last week, couldn't get a straight answer on the yellow screen (got 3 different answers from 3 different people), no loaners, only rentals were 2 remaining ICE vans which rented fast with no more ICE rentals left too, repair estimate was 1-4 days (they did it on 1, so good for them, but the estimate was so long because they have no proper scheduling once the car is waiting on their lot, even though the appointment was scheduled a month in advance), and when we got it back there was weird dirt on the leather seats and door. If this was a dealer, it would be a dealer people would stop going to and they would go out of business soon. With Tesla however there is no choice, they have a monopoly on service (and a conflict of interest too, since the more they fix, the more it costs the company, as opposed to a regular dealer who makes money on everything they fix since they don't share P&L with the manufacturer).
I haven't been to the Seattle Service Center in years, but when I was booking the appointment the wait was also about a month.
